MOVING-PICTURE MACHINE.

Application filed January 15, 1912.

To all whom it may concern: 7

Be it known that I, TOMAS Pnoc'ron HALL, of the city of Vancouver, inthe Province of British Columbia, Canada, have invented certain new anduseful Improvements in Moving-Picture Machines; and I do hereby declarethat the following is a full, clear, and exact description of the same.

This invention relates to an apparatus for projecting moving pictureswithout the objectionable flickering action and has for its object toprovide a simple and improved construction for machines of this type aswill be seen from thefollowing description and claims.

For full comprehension, however, reference must be had to theaccompanying drawings forming a part of this specification in whichsimilar reference characters indicate the-same parts and wherein:

Figure 1 is a plan view partly in horizontal section, of my improvedapparatus, Fig. 2 is a vertical section taken on line 2-2 Fig. 1; F igs. 3 and 4 are enlarged detail views taken a't'right angles to eachother and illustrating the construction of the refleeting deviceincluded in my. invention;

and Fig. 5. is a diagrammatic perspective view ofa portion ofmdyapparatus.

My apparatus inclu es a reflecting device of particular arrangement andform where- .by the image is reflected from the film directly to thescreen upon which the pictures are being projected, thereby eliminatingin machines of this type, the retracting substances heretofore placedintermediate of the reflecting surface and the screen.

Referring now to the drawings the housihg is indicated at b and inclosesthe reels 0 and d upon which the film is wound, passing over rolls f andg mounted on opposite sides of the front aperture lb of" the housing,the

the perforations in the film and bein operative engagement with thedrivin wheel i by gear wheel. 7'. The driving wheel is preferablyrotated by a crank is extending outside the housing, a sprocket andchain connection Z being provided between the driying wheel and thereceiving wheel d, to move the film in the usual manner.

The film is illuminated from a point -outside the housing, the lightpassing through the film c and double convex lens m to a reflectingdevice in line with the film Specification of Letters Patent.

and preferably comprising a series of mirrors n adapted to move inunison with the film when the 'achine is operating. The mirrors which a1substantially the same size as the image upon the film are set at anangle to their carrier and together form a reflecting surface thetransverse axis of which is at an angle tothe transverse axis of thefilm so that when they assumeia posi tion opposite the portion of thefilm being illuminated they are inclined away from the film with theirsurface disposed to defleet the illuminated image from the film to thescreen at a point to one side of the film, through a second aperture 3in the front of the housing at the side of and in a straight line withthe aperture I). (see Fig. 1). The lens m may be supported in a frame 2secu'redto one side wall of the housing and is inclined to assume aposition parallel with the mirror then in line with the image beingilluminated.

To insure the surface of the mirrors (which in the present instance areplane but may be convex to form mirror lenses) coming into properposition relatively to the film that is with the side lines of themirrors parallel with the side lines of the film, I have placed each oneat a slight angle to the adjoining ones as indicated in Figs. 2 and 3.

The mirrors are mounted on a wheel 0 r0- tatably supported in the centerline of the apertures between the side walls of the housing andpresenting near its periphery a circular angularly disposed'fiange p towhich is secured a ring 9 of channel-cross-section and facing outwardlywithin which the mirrors are located, being held in position by lugs 1*upon the ring a and by set screws 8.

In the utilization of the wheel 0 as the carrier for the mirrors thedesired inclination of the latter is obtained by inclining them inwardlyin the longitudinal axial line of the wheel such position being rigidlymaintained by any preferable means as by extending the base of the ring9 and placing a packing member a between the back of the mirrors and thewall of the ring.

The radius of the Wheel 0 is preferably twice the distance between thefilm and the lens and the periphery of the Wheel is provided with teethu which engage with the i the idler 9 being on the opposite side-of thewheel 2'- to that of the wheel 0.

The operation of my apparatus is as follows: The light from a: passesthrough the film and lens thus projecting the image from the film'to oneof the inclined mirrors n the image being then deflected to one side ofthe film again through the lens m and through the aperture 3 to thescreen, the reels, etc, 10 beingso arranged that they do not interferewith the rays, as will be clearly seen in unison with the film themovement of the former is compensated for by the movement of the latterthus when an image is projected by one of the mirrors, the image isstationary until it is gradually displaced and replaced by the image ofthe next portion of the film coming into the focus of the next mirrorand so deflected upon the screen. Thus two partial images deflected fromtwo adjacent mirrors combine to form a complete image upon thecontinuously illuminated screen.

Althou h I have described my invention as applied to a projectingapparatus it will be apparent that it may be utilized to advantage -inphotographing moving objects by closing vthe aperture h, the mirrors nthen reflecting the object from the exterior of the housing to a.sensitized film.

What I claim is as follows 1.
